Description

本発明は、主に家庭で使用し、水道水をろ過する家庭用浄水器に関する。 The present invention relates to a domestic water purifier that is mainly used at home and filters tap water.

近年、水道水を飲用する際、安全でおいしい水を得るために、水道水中のカルキ臭、カビ臭、トリハロメタンなどを浄水器でろ過する傾向が高まっている。浄水器としては、活性炭や中空糸膜などのろ材を充填したカートリッジを装着して使用するものが一般的であり、ろ材の能力が低下したときには、使用者がカートリッジを交換する。 In recent years, when drinking tap water, in order to obtain safe and delicious water, there is an increasing tendency to filter the odor, mold odor, trihalomethane, and the like in tap water with a water purifier. A water purifier is generally used with a cartridge filled with a filter medium such as activated carbon or a hollow fiber membrane. When the capacity of the filter medium is reduced, the user replaces the cartridge.

従来から、カートリッジのろ過能力低下時期をあらかじめ浄水器に表示して、使用者がカートリッジの交換を忘れず行える機能を有した浄水器が知られている（特許文献１）。しかしながら、液晶表示器を用いる表示方法は製造コストがかかり、浄水器が高価になってしまうという問題点があった。
液晶表示器を用いずに交換時期を表示する浄水器としては、ダイヤルやリングに１から１２の月数字を羅列配置で表示し、矢印等の指示部によって次回カートリッジの交換を行う月を示すものがある（特許文献２）。しかしながら、次回交換月を使用者が設定するために、カートリッジのろ過能力が低下する期間を調べ、次回交換月を計算して求める必要があって面倒であるという問題点があった。また計算を間違えたために安全でおいしい水が得られなくなっているのに気が付かないという問題点もあった。また矢印が指示する交換月を見間違うという問題点もあった。
使用者が計算を間違い、次回交換月の表示を間違えることを防ぐために、カートリッジの使用開始時期を矢印に合わせると、もう一方の矢印が次回交換月を指し示す製品もあった。しかし、二つの矢印や月数字の羅列が全て見えるため、次回交換月が明確でなく分かりづらい欠点があった。
逆に、見間違いを防ぐために１から１２の月数字を表示したダイヤルやリングの上に窓を設けたカバーをし、カートリッジの次回交換月のみが窓部から表示されるように改良した浄水器も知られている（特許文献３）。しかしながら、使用者がカートリッジのろ過能力が低下する期間を調べ、次回交換月を計算して求める必要があるのは同様であり、面倒であるという問題点は残されたままであった。さらに、該公知例は円盤状ダイヤルの側面に次回交換時期を示す文字が施され、円盤の平面上に凹凸を設けている。凹凸に相対する凸凹を有する部材の凸凹を撓ませることで、回動する円盤状ダイヤルの位置決めを実施している。しかし、本発明者らの知見によれば、この構造では文字を大きく見やすくするためには円盤状ダイヤルの厚みを大きくする必要がある。ポット型浄水器は冷蔵庫収納を想定したものが多く、外形を大きくすることが難しいため、ダイヤルをフタに設置することが主流のポット型浄水器に用いる場合、厚みの大きいダイヤルを取り付けると、ポット型浄水器の容量が小さくなるという欠点がある。また、円盤の平面上に凹凸を設ける構造はポット型浄水器に適用すると、円盤平面上の凹凸に嵌り合う凸凹部をフタに設ける必要がある。しかし、フタの凹凸を撓ませるためにフタの厚みを小さくするとフタの強度が小さくなる問題があり、フタの厚みを維持した状態でフタにスリットを設け撓ませると、外観の問題だけでなく浄水器内にホコリなどの異物が入るなどの問題が発生する。 2. Description of the Related Art Conventionally, a water purifier has been known that has a function that allows a user to replace a cartridge by displaying the time when the filtration capacity of the cartridge is reduced in advance on the water purifier (Patent Document 1). However, the display method using a liquid crystal display has a problem that it is expensive to manufacture and the water purifier becomes expensive.
As a water purifier that displays the replacement time without using a liquid crystal display, it displays the month numbers from 1 to 12 in a dial arrangement on the dial or ring, and indicates the month when the next cartridge replacement is to be performed by an indicator such as an arrow. (Patent Document 2). However, in order for the user to set the next replacement month, there is a problem that it is troublesome because it is necessary to investigate the period during which the filtration capacity of the cartridge is lowered and calculate the next replacement month. There was also the problem of not realizing that safe and delicious water could not be obtained due to incorrect calculations. There was also a problem that the exchange month indicated by the arrow was wrong.
In order to prevent the user from making a mistake in the calculation and displaying the next replacement month in error, there is a product in which the other arrow indicates the next replacement month when the use start time of the cartridge is aligned with the arrow. However, since all the arrows and month numbers are visible, the next exchange month is not clear and difficult to understand.
On the contrary, in order to prevent mistakes, the water purifier has been improved so that only the next replacement month of the cartridge is displayed from the window, with a cover provided with a window on the dial or ring displaying the month number from 1 to 12. Is also known (Patent Document 3). However, it is the same that the user needs to investigate the period when the filtration capacity of the cartridge is lowered and calculate the next replacement month, and the problem that it is troublesome remains. Further, in this known example, characters indicating the next replacement time are provided on the side surface of the disk-shaped dial, and unevenness is provided on the flat surface of the disk. The rotating disk-shaped dial is positioned by bending the unevenness of the member having the unevenness facing the unevenness. However, according to the knowledge of the present inventors, in this structure, it is necessary to increase the thickness of the disk-shaped dial in order to make the characters large and easy to see. Many pot-type water purifiers are intended for refrigerator storage, and it is difficult to increase the external shape. Therefore, when a dial is installed on the lid, the mainstream pot-type water purifier is used. There is a drawback that the capacity of the water purifier is reduced. Moreover, when the structure which provides unevenness on the flat surface of the disk is applied to a pot-type water purifier, it is necessary to provide the cover with a convex / concave portion that fits the unevenness on the flat surface of the disk. However, if the thickness of the lid is reduced to bend the unevenness of the lid, there is a problem that the strength of the lid is reduced. If the lid is bent with the lid thickness maintained and bent, not only the appearance problem but also water purification Problems such as dust or other foreign matter entering the chamber.

Note that the present invention is not limited to the embodiments described below, and may be any means as long as the object of the present invention can be achieved.
FIG. 1 shows a schematic view of a pot type water purifier which is an embodiment of the present invention. The pot type water purifier includes a main body 1 and a cartridge 2, and the main body 1 includes a main body container 11, a funnel 12, a lid 13, a spout cover 14, and an exchange display dial (display member) 15. A funnel 12 is attached above the main body container 11, and a purified water reservoir 31 is located below. The lid 13 is disposed above the main body container 11 and the funnel 12. The spout cover 14 is connected to a spout cover connecting portion 50 provided on the front side of the lid 13, and an exchange display dial (display member) 15 is disposed on the back side of the lid 13. The cartridge 2 is used in a state in which it is inserted into the cartridge fitting portion 32 opened on the bottom surface of the funnel 12.
FIG. 2 is a longitudinal sectional view of a pot type water purifier cartridge according to an embodiment of the present invention. The cartridge 2 includes a cap 21, a filtration filter 22, and an outer case 23. The filtration filter 22 is connected to the lower center position of the cap 21, and the outer case 23 is connected to the lower side of the cap 21 so as to cover the filtration filter 22.
The filtration filter 22 has a cylindrical outer mesh member 33 and an inner mesh member 34, and the inner space of the inner mesh member 34 serves as a raw water collecting portion 35, and the space between the outer mesh member 33 and the inner mesh member 34 is filled with a filter medium. Part 36.
In the state of FIG. 1, when the lid 13 is removed and tap water is put into the funnel 12, the tap water passes through the cartridge 2 by its own weight, free residual chlorine and the like are removed, and the purified water is stored in the purified water reservoir 31 below the main body container 11 as purified water. Accumulate. When the lid 13 is attached to the funnel 12 attached to the main body container 11 with the purified water stored, and the main body container 11 is tilted, the purified water pushes out the spout cover 14 and flows out to obtain purified water.
In FIG. 2, the tap water put in the funnel 12 passes through the upper opening mesh member 38 from the upper opening 37 of the cap 21, and simultaneously passes through the inner mesh member 34 which is the raw water collecting part 35, and the filter medium filling part. 36. The purified water purified by the filter medium in the filter medium filling section 36 is stored in the purified water storage section 31 through the outer mesh member 33 and six slits provided in the length direction extending to the lower end of the outer case 23.
The main body container 11 will be described with reference to FIGS. 3 is a top view of a main body container according to one embodiment of the present invention, FIG. 4 is a front view of the main body container according to one embodiment of the present invention, and FIG. 5 is a left side surface of the main body container according to one embodiment of the present invention. FIG. 6 is an enlarged view of a portion A in FIG. 5, and FIG. 7 is a right side view of a main body container according to an embodiment of the present invention.
The main body container 11 is a substantially quadrangular prism-shaped liquid storage container consisting of a bottom and a side. A handle 41 is held on one side and held by a user during water injection, and a semicircular cutout is formed on the upper end of the handle 41 side. 77 has a spout 42 which is an inclined portion for pouring purified water on the side surface facing the handle portion 41 and is made of polystyrene. The pot-type water purifier is conveniently a transparent container in which the filtration state and the amount of purified water can be easily confirmed, and highly transparent polystyrene and AS resin (acrylonitrile styrene resin) are preferable. In addition, resin molded products such as polypropylene, polycarbonate, acrylic resin, polyethylene, and ABS resin (acrylonitrile butadiene styrene resin) may be used.

従来においては、本体容器は、持ち運びやすさや注ぎやすさの利点より取っ手が設けられている形状が多い（特許文献６）。しかし、取っ手があることで本体容器全体が大きくなり、特に冷蔵庫など限られたスペースに収納する際、他のものが収納できなくなる問題が発生する。そこで取っ手のない本体容器が考案された（特許文献７）。この場合、本体容器の側面を窪ませることで、持ちやすい形状とすることが多い。射出成形でつくられる本体容器は上端に近づくにつれ大きくなるため、上方でも持ちやすいように上端の幅を狭く大きな窪みをつけることになるが、下端はさらに幅が狭く全体の容量が小さくなる問題がある。ポット型浄水器は上半分にロートが位置するので下半分にしか浄水が溜められず、浄水貯留部の容量確保が難しい。そこで、ロートに窪みを設けずに浅くても水道水貯留部の体積が大きくなる形状を採用し、浄水貯留部にのみ窪みを設け容量を確保するなど、窪みを上端から設けないものが増えている（特許文献７）。しかし、本体容器の上方に窪みがないため指をかけて握ることができず、使用者には使いづらいという問題がある。
本実施形態においては、持ち手部４１は冷水筒で一般的に採用されている取っ手形状でもよいが、図４のように本体容器１１の側面を利用した形状とする。冷蔵庫へ収納する際、省スペースとなり、使いやすい。指をかけられるような水平断面凹部４３を設けて持ち手部４１としているため持ち運びやすい利点もある。本体容器の金型に抜き勾配を設けるため、上方に行くに従い持ち手部４１の幅が広くなるが、水平断面凹部４３に隣接する凸部７６の一部を小さくし、水平断面凹部４３を大きくした持ち手位置６５を設け、持ち手部４１の幅の一部を狭くしているので、持ち手部４１の上方であっても持ちやすい形状となっている。持ち手部４１の幅が狭く持ちやすい下方を持って持ち運びすると、浄水貯水部３１とカートリッジ２に浄水が入った状態では、浄水器全体の重心が使用者の手の位置より上方に来て不安定になるが、水平方向の凹部６５を持ち手部４１の上半分側に設け、持ち手部４１の幅の一部を狭く持ちやすくすることで使用者の手が浄水器全体の重心より上方に位置し、安定して持ち運ぶことができる効果が得られる。
従来においては、本体容器を傾け注ぐと、浄水の流れ出る力で注ぎ口上のカバーが勝手に開くように、注ぎ口を覆う部品をフタと別パーツで設けてフタに取り付ける構造が多い（特許文献１）。しかし、本発明者らの知見によると、注ぎ口上のカバーを浄水の流れ出る力だけで開閉させる場合、注ぎ口上のカバーが大きいもしくは重いと、スムーズな開閉ができない問題がある。特に注ぎ始めは注ぎ口上のカバーが十分に開いていないため、注ぎ口上のカバーの大きさに近い幅広い状態で浄水が流れ出し、注ぎにくい問題がある。さらに、注ぎ口の上端が濡れている場合、水の表面張力により本体容器と注ぎ口上のカバーが張り付いており、注ぎ口上のカバーが開くまでに時間がかかる。浄水が注ぎ口上のカバーに溜まった後、注ぎ口カバーが突然開いて一気に浄水が出るため注ぎづらい。本体容器の注ぎ口を大きく突き出して形成すると浄水が勢いよく流れ出し注ぎ口カバーを押し開く力が増すため、注ぎ口カバーが浄水の流出を阻害せず注ぎやすい浄水形状が得られる。しかし、収納スペースを取る形状となり不便である。また、注ぎ口上のカバーを別パーツとせず、フタの一部で注ぎ口上を覆うと、使用の度にフタの開閉を行う必要があり不便である。また、使用時に使用者がフタの開閉を行う必要がないよう、本体容器の注ぎ口が大きく切り欠かれ、本体容器を傾けるとその切り欠きから浄水が流れ出る形状になっているものもある。しかし、この形状は切り欠きが大きいために、保存状態においても浄水にホコリや異物が入りやすい問題がある。
本実施形態においては、浄水を注ぐための傾斜部である注ぎ口４２は浄水貯水部３１から突き出して形成され、上端先端に切り欠き４４を設けている。切り欠き４４を設けることで注ぎ口４２と注ぎ口カバー１４との接触面積が小さくなる。
注ぎ口上端が濡れている場合も、本体容器と注ぎ口上のカバーの張り付き力が小さくなるため、浄水を注ぐ際に、注ぎ口カバー１４の開閉がスムーズになる。また注ぎ口カバー１４が十分に開いていない注ぎ始めも、切り欠き４４を通して浄水が流れ出るため、切り欠き４４がない場合よりも浄水が勢いよく流れ出し、その勢いで注ぎ口カバー１４が開きやすくなる効果がある。浄水が注ぎ口上のカバーに溜まった後、注ぎ口カバー１４が突然開いて一気に浄水が出る問題も解消でき、本体容器１１の注ぎ口４２を大きく突き出して形成する必要がなくなるため省スペースの設計が可能となる。切り欠き４４は特に、注ぎ口４２と注ぎ口カバー１４の接触面積の低減と、注ぎ始めの浄水流路確保が目的であるため、フタの一部で注ぎ口上を覆う形状ほど大きく切り欠く必要がなく、特に切り欠き４４の最大幅Ｄと最大高さＨが０．１＜Ｈ／Ｄ＜１０であると、上記目的と、保存時の異物混入防止のどちらも満たすことができ、望ましい。さらに切り欠き４４は本体容器１１を注ぎ口４２側から見て略三角形もしくは略半円であると、浄水の流れ出る勢いが高まるためより望ましい。
図８〜１３を用いてロート１２について説明する。図８は本発明の一実施形態に係るロートの上面図、図９は本発明の一実施形態に係るロートの正面図、図１０は本発明の一実施形態に係るロートの正面断面図、図１１本発明の一実施形態に係るロートの下面図である。
ロート１２は底面と側面で構成され、底面にカートリッジを挿入するためのカートリッジ嵌合部３２を有するプラスチック容器であり、上部外側で本体容器１１と、上部内側でフタ１３と嵌合する。材料は透明性に優れるポリスチレンを使用しているため、水道水のろ過状態が確認しやすい。ポリプロピレンやＡＳ樹脂、ポリカーボネート、アクリル樹脂、ポリエチレン、ＡＢＳ樹脂などであっても良い。
ロート１２は本体容器１１と本体容器嵌合部４５で嵌合する。本体容器嵌合部４５には外側に突き出す凸で本体容器嵌合リブ４６がある。本体容器嵌合リブ４６の厚みを調整して本体容器１１との嵌合強度を高めているので、フタ１３を外す際にロート１２と本体容器１１の固定が維持され使いやすい。本体容器嵌合リブ４６を持ち手部４１側に設けているので注ぎ口側の本体容器１１とロート１２がしっかり嵌合しており、隙間から漏れ出ることなく、浄水を安定して注ぐことができる。本体容器嵌合リブ４６の変わりに、ロートに凸部を、本体容器に凹部を設けて、かみ合わせるようにすればさらに嵌合強度が高まる。
ロート１２とフタ１３は、ロートのフタ嵌合部４７およびフタのロート嵌合部４９の全周を利用して嵌合させている。ロート１２の一部に寸法管理用直線部４８を設けておくと、ノギスなど接触機器で寸法が容易かつ精度良く測定することができ好ましい。
ロート１２の上端外形は、図１２のように上面から見て本体容器１１の注ぎ口４２を略円形に開放する形状になっている。略円形の空間とすることで、流出する浄水のまとまりを良くし、注ぎ口カバー１４の大きさや形状に関係なく注ぎやすい浄水形状を得ることができる。例えば、注ぎ口カバー１４が幅広い形状であった場合、ロート１２の外形が略円形の空間を設けることができない形状であると、浄水は注ぎ口カバー１４と同じ幅広い形状で流出する。ロート１２により図１１のように略円形の空間を設けると、浄水が略円形の断面を有して流出するため、注ぎ口カバー１４の幅に影響されることなく注ぎやすいまとまりのある浄水を得ることが可能となる。
ロート１２の下方外形は、図１１のように本体容器１１の注ぎ口４２側にあたる側面が、水平方向に窪んでいる。下方を窪ませることで、図１３のように注ぎ口４２との空間が大きくなり、浄水を一気に注ぐ場合もスムーズに流出できる効果がある。
次にフタ１３について図１４〜２０を用いて説明する。図１４は本発明の一実施形態に係るフタの上面図、図１５は本発明の一実施形態に係るフタの正面図、図１６は本発明の一実施形態に係るフタの右側面図、図１７は本発明の一実施形態に係るフタの正面断面図、図１８は図１７におけるＢ部分拡大図、図１９は本発明の一実施形態に係るフタの下面図、図２０は図１９におけるＣ部分拡大図を示したものである。
フタ１３は注ぎ口カバー１４および交換表示ダイヤル１５を取り付けるプラスチック部材であり、材料にはハイインパクトポリスチレンを用いている。取り付ける部材が多く着脱を繰り返すため、成形精度が高く、かつ、割れたり欠けたりしない樹脂で形成させることが好ましく、ハイインパクトポリスチレンやＡＢＳ樹脂が望ましい。その他にもポリプロピレンやＡＳ樹脂、ポリスチレン、ポリカーボネート、アクリル樹脂、ポリエチレンなど使用可能である。
フタ１３は本体容器１１の外周と略同一の外周を有する楕円状の平部材である。フタ１３の天面一端には注ぎ口カバー接続部５０があり、注ぎ口カバー１４のフタ接続部６６をフタ１３の上から取り付けられるようになっている。注ぎ口カバー接続部５０側に指をかけるための大きな天面凹部６３があり、天面凹部６３の注ぎ口カバー接続部５０寄り底面には、交換表示ダイヤル（表示部材）１５に設けたカートリッジ交換時期を見えるようにする表示窓５２が楕円状に設けてある。裏面にはロート１２と嵌合するロート嵌合部４９が、薄いリブ状でフタ１３を一周している。注ぎ口カバー接続部５０と反対側には、ロート嵌合部４９より外周に薄いリブ状の指掛部６４を設けており、天面の天面凹部６３と指掛部６４でフタ１３をつかめる形状になっている。裏面中央より注ぎ口カバー接続部５０寄りには交換表示ダイヤル接続部５１が軸で形成されている。軸は先端の径が軸中央部の径より大きく、放射状に４分割した形状で、軸中心方向にたわむことが可能であるため交換表示ダイヤル１５の脱着を可能としている。交換表示ダイヤル１５を取り付けた際、交換表示ダイヤル１５を収納する交換表示ダイヤル収納部５３を、リブ状の交換表示ダイヤル収納側面５４で交換表示ダイヤル１５全周を取り囲むことで構成しており、指掛部６４側の交換表示ダイヤル収納側面５４に交換表示ダイヤル１５を取り外すための切り欠き５５がある。
フタ１３はリブ状のロート嵌合部４９全周でロート１２と嵌合する。ロート嵌合部４９の、フタ１３の長手方向内側に寸法管理用直線部４８を設けているため、ノギスなど接触機器で寸法が容易かつ精度良く測定することができる。
フタ１３は天面に大きな天面凹部６３を有し、リブ状のロート嵌合部４９より外側に指掛部６４を有する。天面凹部６３は深さが１０ｍｍ程度で、指がかけられる。指掛部６４は、外周面が本体容器１１の外周面と略同一となるよう、本体容器１１の持ち手部４１側上端に設けられた半円状の切り欠き７７に重なる位置に、フタ１３の裏面から略鉛直下向きに半円状で形成される。指掛部６４は本体容器１１の外周より外側に位置しても良いが、切り欠き７７に嵌り、外周面が本体容器１１の外周面と同一となる形状としているためコンパクトであり収納しやすい本体が得られる。また、指掛部６４は切り欠き７７の上方のみに存在する形状でも良いが、切り欠き７７とほぼ同じ大きさと形状を用いているため、指掛部６４の面積が広くなり、フタを安定して支えることができる。
フタ１３の天面には指をかけるための大きな天面凹部６３がある。フタ１３が本体容器１１の外形と略同一であり外周の段差が小さくフタ１３に指をかけにくい形状の場合も、天面凹部６３に指をかけることでフタ１３の着脱が容易にできる。特に外周の段差が５ｍｍ以下の場合に効果がある。天面凹部６３の側面を水平方向に窪ませることでより指をかけやすくする形状が考えられるが、フタ１３を作る際必要な金型コストが高くなる問題がある。天面凹部６３と指掛部６４を有する形状にすることで、天面凹部６３と指掛部６４に指をかけフタ１３を挟んで着脱できるため、天面凹部６３の側面を水平方向に窪ませる必要がなくなる。金型コストを維持したままフタ１３を容易に着脱できる形状を実現することが可能となる。指掛部６４は指を当て添えフタ１３を支持する部分であるため、最大幅１０ｍｍ以上かつ最大高さ３ｍｍ以上であることが好ましい。幅はフタ１３の天面に対し平行方向、高さはフタ１３の天面に対し垂直方向とした。指掛部６４の先端に向かうにつれ薄くなると金型からの離型性が向上するため生産性が良い利点がある。天面凹部６３を指掛部６４と同時に設ける場合、天面凹部６３は幅１０ｍｍ以上かつ深さ３ｍｍ以上あれば指をかけることができる。また、天面凹部６３は凸形状でも同様の効果を得ることができる。凸形状の場合も幅１０ｍｍ以上かつ高さ３ｍｍ以上あれば指をかけることができ、指掛部６４と同時に設けることで凸形状の高さが小さくてもフタ１３をつまむことができ、容量の確保も実現できる。
注ぎ口カバー接続部５０は、浄水が注ぎ口カバー１４を押し開きやすいよう、軸と軸受けで接続する構造にしている。本実施形態では注ぎ口カバー１４のフタ接続部６６に軸受けを設けているが、フタ１３の注ぎ口カバー接続部５０に軸受けを設け、注ぎ口カバー１４のフタ接続部６６に軸を設けてもよい。
交換表示ダイヤル接続部５１は、交換表示ダイヤル（表示部材）１５を取り付ける軸を有している。交換表示ダイヤル１５はビスやキーなどの留め具を利用して取り付けてもよいが、嵌め合いで取り付ける方が材料費や組立費が少なく安価で好ましい。
フタ１３に表示窓５２を設け、カートリッジの交換時期だけを表示する構造としているので交換時期が分かりやすく、スッキリした外観が得られている。表示窓５２は穴を設けてもよいし、透明樹脂で窓を設けてもよい。
交換表示ダイヤル収納部５３を設け、交換表示ダイヤル収納部側面５４で交換表示ダイヤル１５を囲う構造としているので、フタ１３の裏面についた水滴が交換表示ダイヤル１５の上面にかかりにくく溜まらないため衛生的である。また外観がスッキリする効果も得られている。交換表示ダイヤル収納部側面５４の一部に交換表示ダイヤル取り外し用切り欠き５５を設けているので、交換表示ダイヤル収納部側面５４で交換表示ダイヤル１５を全周囲っても交換表示ダイヤル１５の取り外しが容易に行える。交換表示ダイヤル収納部５３内側に交換表示ダイヤル支持リブ７８を２本設けているので、交換表示ダイヤル１５の傾きを防止することができる。交換表示ダイヤル支持リブ７８は複数本設けると、交換表示ダイヤル１５の傾き防止効果がより高まる。
フタ１３と交換表示ダイヤル（表示部材）１５を交換表示カレンダー５８以外の位置で当接させることを目的とした交換表示ダイヤル保護リブ５９を設けている。 Conventionally, a main body container has many shapes in which the handle is provided from the advantage of carrying around and pouring ease (patent document 6). However, due to the presence of the handle, the entire main body container becomes large. In particular, when storing in a limited space such as a refrigerator, there arises a problem that other things cannot be stored. Therefore, a main body container without a handle was devised (Patent Document 7). In this case, the side surface of the main body container is often recessed to make it easy to hold. Since the main body container made by injection molding becomes larger as it approaches the upper end, the upper end is narrower and has a large depression so that it can be easily held in the upper part, but the lower end is narrower and the overall capacity is reduced. is there. Since the pot type water purifier has a funnel in the upper half, the purified water can be collected only in the lower half, and it is difficult to secure the capacity of the purified water storage section. Therefore, adopting a shape that increases the volume of the tap water storage part even if it is shallow without providing a recess in the funnel, and providing a recess only in the purified water storage part to ensure capacity, etc. (Patent Document 7). However, since there is no depression above the main body container, it cannot be gripped with a finger, and there is a problem that it is difficult for the user to use.
In the present embodiment, the handle portion 41 may have a handle shape generally employed in a cold water cylinder, but has a shape utilizing the side surface of the main body container 11 as shown in FIG. When stored in the refrigerator, it is space-saving and easy to use. There is also an advantage that it is easy to carry because the holding section 41 is provided with a horizontal cross-section recess 43 that can be put on a finger. In order to provide a draft in the mold of the main body container, the width of the handle portion 41 becomes wider as it goes upward, but a part of the convex portion 76 adjacent to the horizontal cross-section concave portion 43 is made small and the horizontal cross-section concave portion 43 is made large. Since the handle position 65 is provided and a part of the width of the handle portion 41 is narrowed, the shape is easy to hold even above the handle portion 41. If the handle portion 41 is carried with a narrow and easy-to-hold lower part, the center of gravity of the entire water purifier will be higher than the position of the user's hand when the purified water is stored in the purified water storage unit 31 and the cartridge 2. Although it becomes stable, a user's hand is above the center of gravity of the entire water purifier by providing a horizontal recess 65 on the upper half side of the handle portion 41 and making it easier to hold a part of the width of the handle portion 41 narrower. The effect that it is located in and can be carried stably is acquired.
Conventionally, when the main body container is tilted and poured, the structure that covers the spout is provided separately from the lid and attached to the lid so that the cover on the spout can be opened without permission by the flow of purified water (Patent Document 1). ). However, according to the knowledge of the present inventors, when the cover on the spout is opened and closed only with the force of flowing clean water, there is a problem that smooth opening and closing cannot be performed if the cover on the spout is large or heavy. In particular, since the cover on the spout is not sufficiently opened at the beginning of pouring, there is a problem that the purified water flows out in a wide state close to the size of the cover on the spout and is difficult to pour. Furthermore, when the upper end of the spout is wet, the main body container and the cover on the spout are stuck due to the surface tension of water, and it takes time to open the cover on the spout. After clean water has accumulated in the cover on the spout, the spout cover suddenly opens and it is difficult to pour because the clean water comes out at once. If the pour spout of the main body container is protruded greatly, the clean water flows out vigorously and the force for opening the pour spout cover increases, so that the pour spout cover does not hinder the outflow of clean water and can be poured easily. However, it takes a storage space and is inconvenient. If the cover on the spout is not a separate part and the top of the spout is covered with a part of the lid, it is inconvenient because the lid needs to be opened and closed each time it is used. In addition, there is a shape in which the spout of the main body container is greatly cut out so that the user does not need to open and close the lid during use, and when the main body container is tilted, purified water flows out from the notch. However, since this shape has a large notch, there is a problem that dust and foreign substances are likely to enter the purified water even in a stored state.
In this embodiment, the spout 42 which is an inclined part for pouring purified water protrudes from the purified water storage part 31 and is provided with a notch 44 at the top end. By providing the notch 44, the contact area between the spout 42 and the spout cover 14 is reduced.
Even when the upper end of the spout is wet, since the sticking force between the main body container and the cover on the spout becomes small, the opening and closing of the spout cover 14 becomes smooth when pouring clean water. Further, even when the pour spout cover 14 is not fully opened, the purified water flows out through the notch 44. Therefore, the purified water flows out more vigorously than the case where there is no notch 44, and the spout cover 14 can be easily opened with this momentum. There is. After the purified water has accumulated in the cover on the spout, the problem that the spout cover 14 suddenly opens and the purified water comes out at once can be solved, and there is no need to project the spout 42 of the main body container 11 so that the space-saving design is eliminated. It becomes possible. In particular, the notch 44 is intended to reduce the contact area between the spout 42 and the spout cover 14 and to secure a purified water flow path at the beginning of pouring. In particular, it is preferable that the maximum width D and the maximum height H of the notch 44 satisfy 0.1 <H / D <10, since both the above-mentioned purpose and prevention of foreign matter contamination during storage can be satisfied. Furthermore, it is more desirable that the notch 44 is substantially triangular or substantially semicircular when the main body container 11 is viewed from the side of the spout 42 because the momentum of the purified water flowing out increases.
The funnel 12 will be described with reference to FIGS. 8 is a top view of the funnel according to the embodiment of the present invention, FIG. 9 is a front view of the funnel according to the embodiment of the present invention, and FIG. 10 is a front sectional view of the funnel according to the embodiment of the present invention. 11 is a bottom view of a funnel according to an embodiment of the present invention. FIG.
The funnel 12 is composed of a bottom surface and a side surface, and is a plastic container having a cartridge fitting portion 32 for inserting a cartridge into the bottom surface. The funnel 12 is fitted to the main body container 11 on the upper outer side and the lid 13 on the upper inner side. Since the material uses polystyrene with excellent transparency, it is easy to confirm the filtered state of tap water. Polypropylene, AS resin, polycarbonate, acrylic resin, polyethylene, ABS resin, or the like may be used.
The funnel 12 is fitted by the main body container 11 and the main body container fitting portion 45. The main body container fitting portion 45 has a main body container fitting rib 46 with a convex protruding outward. Since the fitting strength with the main body container 11 is increased by adjusting the thickness of the main body container fitting rib 46, when the lid 13 is removed, the funnel 12 and the main body container 11 are fixed and easy to use. Since the main body container fitting rib 46 is provided on the handle 41 side, the main body container 11 on the spout side and the funnel 12 are firmly fitted, and water can be poured stably without leaking from the gap. it can. Instead of the main body container fitting rib 46, a convex portion is provided in the funnel and a concave portion is provided in the main body container so that the fitting strength is further increased.
The funnel 12 and the lid 13 are fitted using the entire circumference of the funnel lid fitting portion 47 and the funnel fitting portion 49 of the lid. It is preferable to provide a dimension management linear portion 48 in a part of the funnel 12 because the dimensions can be easily and accurately measured with a contact device such as a caliper.
As shown in FIG. 12, the upper end outer shape of the funnel 12 has a shape that opens the spout 42 of the main body container 11 in a substantially circular shape when viewed from above. By setting it as a substantially circular space, the collection of the purified water flowing out can be improved, and a purified water shape that is easy to pour can be obtained regardless of the size and shape of the spout cover 14. For example, when the spout cover 14 has a wide shape, the clean water flows out in the same wide shape as the spout cover 14 if the outer shape of the funnel 12 is a shape that cannot provide a substantially circular space. When a substantially circular space is provided by the funnel 12 as shown in FIG. 11, the purified water flows out with a substantially circular cross section, so that it is easy to pour water without being affected by the width of the spout cover 14. It becomes possible.
As for the lower external shape of the funnel 12, the side surface corresponding to the spout 42 side of the main body container 11 is recessed in the horizontal direction as shown in FIG. By recessing the lower part, the space with the spout 42 becomes larger as shown in FIG. 13, and there is an effect that the water can flow smoothly even when purified water is poured at once.
Next, the lid 13 will be described with reference to FIGS. 14 is a top view of a lid according to an embodiment of the present invention, FIG. 15 is a front view of the lid according to an embodiment of the present invention, and FIG. 16 is a right side view of the lid according to the embodiment of the present invention. 17 is a front sectional view of a lid according to an embodiment of the present invention, FIG. 18 is an enlarged view of a portion B in FIG. 17, FIG. 19 is a bottom view of the lid according to an embodiment of the present invention, and FIG. A partially enlarged view is shown.
The lid 13 is a plastic member to which the spout cover 14 and the exchange display dial 15 are attached, and high impact polystyrene is used as the material. Since many members are attached and repeatedly attached and detached, it is preferable to form the resin with high molding accuracy and a resin that does not crack or chip, and high impact polystyrene or ABS resin is desirable. In addition, polypropylene, AS resin, polystyrene, polycarbonate, acrylic resin, polyethylene, and the like can be used.
The lid 13 is an elliptical flat member having substantially the same outer periphery as that of the main body container 11. There is a spout cover connecting portion 50 at one end of the top surface of the lid 13, and a lid connecting portion 66 of the spout cover 14 can be attached from above the lid 13. There is a large top surface concave portion 63 for placing a finger on the spout cover connecting portion 50 side, and the cartridge provided on the replacement display dial (display member) 15 is disposed on the bottom surface of the top surface concave portion 63 near the spout cover connecting portion 50. A display window 52 for making the time visible is provided in an elliptical shape. A funnel fitting portion 49 that fits with the funnel 12 wraps around the lid 13 in a thin rib shape on the back surface. On the opposite side to the spout cover connecting portion 50, a thin rib-like finger hook portion 64 is provided on the outer periphery of the funnel fitting portion 49, and the lid 13 can be held by the top concave portion 63 and the finger hook portion 64 on the top surface. It has a shape. An exchange display dial connection portion 51 is formed on the shaft near the spout cover connection portion 50 from the center of the back surface. The shaft has a tip having a diameter larger than that of the central portion of the shaft and is radially divided into four parts, and can be bent in the axial center direction, so that the replacement display dial 15 can be attached and detached. When the exchange display dial 15 is attached, the exchange display dial storage section 53 for storing the exchange display dial 15 is configured by surrounding the entire circumference of the exchange display dial 15 with a rib-shaped exchange display dial storage side surface 54. A cutout 55 for removing the exchange display dial 15 is provided on the exchange display dial storage side surface 54 on the hanging portion 64 side.
The lid 13 is fitted to the funnel 12 along the entire circumference of the rib-like funnel fitting portion 49. Since the linear portion 48 for dimension management is provided inside the funnel fitting portion 49 in the longitudinal direction of the lid 13, the dimensions can be measured easily and accurately with a contact device such as a caliper.
The lid 13 has a large top surface recess 63 on the top surface, and has a finger hook portion 64 outside the rib-shaped funnel fitting portion 49. The top recess 63 has a depth of about 10 mm and can be put on with a finger. The finger hook portion 64 is located at a position overlapping the semicircular cutout 77 provided at the upper end of the main body container 11 on the handle portion 41 side so that the outer peripheral surface is substantially the same as the outer peripheral surface of the main body container 11. Is formed in a semicircular shape substantially vertically downward from the back surface. The finger hook portion 64 may be positioned outside the outer periphery of the main body container 11, but the main body is compact and easy to store because it fits into the notch 77 and the outer peripheral surface is the same as the outer peripheral surface of the main body container 11. Is obtained. The finger hook portion 64 may have a shape that exists only above the notch 77. However, since the finger hook portion 64 has substantially the same size and shape as the notch 77, the area of the finger hook portion 64 is increased, and the lid is stabilized. Can be supported.
The top surface of the lid 13 has a large top surface recess 63 for placing a finger. Even when the lid 13 is substantially the same as the outer shape of the main body container 11 and the outer peripheral step is small and it is difficult to put a finger on the lid 13, the lid 13 can be easily attached and detached by putting the finger on the top recess 63. This is particularly effective when the outer peripheral step is 5 mm or less. Although the shape which makes it easier to put a finger by concaving the side surface of the top surface recessed part 63 in the horizontal direction can be considered, there is a problem that the mold cost required for making the lid 13 becomes high. By forming the top surface recess 63 and the finger hook portion 64 into a shape, the top surface recess 63 and the finger hook portion 64 can be put on and removed with the lid 13 interposed therebetween, so that the side surface of the top surface recess 63 is recessed horizontally. There is no need to do it. It is possible to realize a shape in which the lid 13 can be easily attached and detached while maintaining the mold cost. Since the finger hook portion 64 is a portion that supports the lid 13 with a finger applied, it is preferable that the finger hook portion 64 has a maximum width of 10 mm or more and a maximum height of 3 mm or more. The width was parallel to the top surface of the lid 13, and the height was perpendicular to the top surface of the lid 13. If the thickness becomes thinner toward the tip of the finger hook portion 64, there is an advantage that productivity is good because releasability from the mold is improved. When the top surface recess 63 is provided at the same time as the finger hook portion 64, the top surface recess 63 can be put on the finger if the width is 10 mm or more and the depth is 3 mm or more. Further, the same effect can be obtained even if the top recess 63 is convex. Even in the case of a convex shape, a finger can be placed if the width is 10 mm or more and the height is 3 mm or more, and the lid 13 can be pinched even if the height of the convex shape is small by providing it at the same time as the finger hook portion 64. Securement can also be realized.
The spout cover connecting portion 50 is structured to be connected with a shaft and a bearing so that clean water can easily push the spout cover 14 open. In this embodiment, a bearing is provided on the lid connecting portion 66 of the spout cover 14, but a bearing may be provided on the spout cover connecting portion 50 of the lid 13 and a shaft may be provided on the lid connecting portion 66 of the spout cover 14. Good.
The exchange display dial connection unit 51 has a shaft to which the exchange display dial (display member) 15 is attached. The exchange display dial 15 may be attached by using a fastener such as a screw or a key. However, it is preferable that the replacement display dial 15 is fitted by fitting because the material cost and assembly cost are low.
Since the display window 52 is provided on the lid 13 to display only the replacement time of the cartridge, the replacement time is easy to understand, and a clean appearance is obtained. The display window 52 may be provided with a hole, or may be provided with a transparent resin.
Since the replacement display dial storage portion 53 is provided and the replacement display dial 15 is enclosed by the side surface 54 of the replacement display dial storage portion, water drops on the back surface of the lid 13 are not easily applied to the upper surface of the replacement display dial 15 and are not collected. It is. Moreover, the effect that the external appearance is refreshing is also acquired. Since the notch 55 for removing the exchange display dial is provided in a part of the side face 54 of the exchange display dial storage part, the exchange display dial 15 can be removed even if the exchange display dial 15 is entirely surrounded by the side face 54 of the exchange display dial storage part. Easy to do. Since the two replacement display dial support ribs 78 are provided inside the replacement display dial storage portion 53, the replacement display dial 15 can be prevented from being inclined. When a plurality of exchange display dial support ribs 78 are provided, the effect of preventing the exchange display dial 15 from tilting is further enhanced.
An exchange display dial protective rib 59 is provided for the purpose of bringing the lid 13 and the exchange display dial (display member) 15 into contact with each other at a position other than the exchange display calendar 58.

従来においては、交換月など日付を表すものには成形で文字を形成するものや印刷を施すものがある。しかし、成形で文字を形成すると、文字と土台を同じ樹脂で成形することになり、色が同じであるため文字が読みづらく、交換時期に気づかない問題がある。交換時期を明確にするため、二色成形で実施する場合も正確に文字だけを着色することは難しく生産性が低い問題が発生する。そこで、成形品に印刷を施す方法が一般的に用いられるようになった。しかし、ダイヤルの回動など部材を移動させる際、印刷した文字が磨耗により削り取られ読めなくなる問題が発生し、印刷を保護するためコーティングを実施する方法（特許文献４）が一般的となっている。しかし、コーティングを施すとコストが高くなり、液晶表示器をダイヤルに変更した利点が相殺される問題がある。
本実施形態においては、交換表示ダイヤル１５の回動操作による当接部の摩擦で交換表示カレンダー５８が摩耗することを防ぐ効果がある。また、交換表示ダイヤル保護リブ５９の断面形状を半円状にしているため、交換表示ダイヤル１５と当接する部分が小さくなり、回動操作がスムーズにできる。 Conventionally, there are those that form a letter by molding and those that print a date, such as a replacement month. However, when a character is formed by molding, the character and the base are molded with the same resin, and since the colors are the same, it is difficult to read the character and there is a problem that the replacement time is not noticed. In order to clarify the replacement time, it is difficult to accurately color only characters even when the two-color molding is performed, resulting in a problem of low productivity. Therefore, a method of printing on a molded product has been generally used. However, when moving a member such as turning a dial, there is a problem that printed characters are scraped off due to wear and cannot be read, and a method of performing coating to protect printing (Patent Document 4) is common. . However, when the coating is applied, the cost increases, and there is a problem that the advantage of changing the liquid crystal display to a dial is offset.
In the present embodiment, there is an effect of preventing the replacement display calendar 58 from being worn by the friction of the contact portion caused by the rotation operation of the replacement display dial 15. In addition, since the cross-sectional shape of the replacement display dial protection rib 59 is semicircular, the portion in contact with the replacement display dial 15 is reduced, and the rotation operation can be performed smoothly.

次に図２１と図２２により注ぎ口カバー１４について説明する。図２１は本発明の一実施形態に係る注ぎ口カバーの正面図、図２２は本発明の一実施形態に係る注ぎ口カバーの下面図を示したものである。
注ぎ口カバー１４は略三角形状の平らなプラスチック部材であり、略三角形状の一辺でフタ１３に接続されている。フタ接続部６６はフタ１３の注ぎ口が取り付けられる接続部５０の軸に対する軸受け形状であり、材料はハイインパクトポリスチレンを用いている。ポリプロピレンやＡＢＳ樹脂などであっても良い。特にハイインパクトポリスチレンやＡＢＳ樹脂は成形精度に優れるため軸や軸受けを精度良く製作することができる。また、ポリプロピレンは比重が軽いため浄水が注ぎ口カバー１４を押し開けやすく、さらに粘性が高いため軸や軸受けが欠けにくく使用者が着脱しやすい効果がある。 Next, the spout cover 14 will be described with reference to FIGS. FIG. 21 is a front view of a spout cover according to an embodiment of the present invention, and FIG. 22 is a bottom view of the spout cover according to an embodiment of the present invention.
The spout cover 14 is a substantially triangular flat plastic member, and is connected to the lid 13 at one side of the substantially triangular shape. The lid connecting portion 66 has a bearing shape with respect to the shaft of the connecting portion 50 to which the spout of the lid 13 is attached, and the material is high impact polystyrene. Polypropylene or ABS resin may be used. In particular, since high impact polystyrene and ABS resin are excellent in molding accuracy, shafts and bearings can be manufactured with high accuracy. In addition, since polypropylene has a low specific gravity, it is easy for purified water to push the spout cover 14 open, and since the viscosity is high, there is an effect that the shaft and the bearing are hardly chipped and the user can easily attach and detach.

交換表示ダイヤル１５について図２３と図２４と図２５により説明する。図２３は本発明の一実施形態に係る交換表示ダイヤルの上面図、図２４は本発明の一実施形態に係る交換表示ダイヤルの正面断面図および正面図、図２５は本発明の一実施形態に係る交換表示ダイヤルの下面図を示したものである。
交換表示ダイヤル１５は中央にくぼみがある円盤状の部材である。中央のくぼみは雫型で裏側から交換表示ダイヤル１５を回動させるためのつまみ７３になっている。フタ１３の交換表示ダイヤル接続部５１の軸を挿入し取り付けるためのフタ接続部７０を、くぼみの中心に円筒形状で設けている。側面には複数の位置決め凹部７１があり、くぼみの底面に、交換表示ダイヤル１５内に入った水を抜くための水抜き穴７２を設けている。円盤部の表面は交換時期表示面７４とし交換時期カレンダー５８がパッド印刷で施されている。裏面は使用開始時期表示面７５として使用開始時期カレンダー６１を０．３ｍｍ高さの刻印で表している。材料は成形精度が良いＡＢＳ樹脂を使用しているが、その他、ポリプロピレンやハイインパクトポリスチレンなどであっても良い。
交換表示ダイヤル１５裏側につまみ７３を設けているため、使用者が動かしやすい形状となっている。交換時期カレンダー５８と使用開始時期カレンダー６１はそれぞれ刻印を設けても印刷を施してもよい。交換時期カレンダー５８に印刷を施すと使用者が見やすく使いやすい効果がある。一方で、使用開始時期カレンダー６１は刻印で設けると、安価に製造できて良い。使用開始時期カレンダー６１を０．３ｍｍ高さで設けているので、交換表示カレンダー５８の印刷面に成形による凹凸の発生を予防しながら、読みとりやすい文字を実現することができる。
交換時期は交換月、交換週、交換日などの表記方法があるが、交換時期を細分化して表記すると使用者に分かりやすい。使用開始時期も同様の理由により細分化することが好ましい。本実施形態の交換表示ダイヤルを大きな円盤にし、上面に交換時期を、裏側に使用開始時期をそれぞれ表すことで、交換時期および使用開始時期をより細分化して表示することができ、使用者に明確な時期を伝えられる効果がある。
交換表示ダイヤル１５が位置するフタ１３裏面の交換表示ダイヤル収納部側面５４の内側に、交換表示ダイヤル１５の側面に設けた複数の位置決め凹部７１に嵌り、交換表示ダイヤル１５の位置決めを行う位置決め凸部５６を設け、位置決め凸部５６の両サイドにスリット５７を入れ、位置決め凸部５６が交換表示ダイヤル１５の回転に伴いたわむことが可能な形状としている。使用者は交換表示ダイヤル１５を楽に回動させることができる。
また位置決め凸部５６と位置決め凹部７１を半円状にしているため、交換表示ダイヤル１５をさらに容易に回動させることができる。
位置決め凸部５６と位置決め凹部７１がかみ合い、交換表示ダイヤル１５の位置決めを行う際、カートリッジの交換時期を示す各文字が表示窓５２の位置で止まるよう配置している。使用者が交換表示ダイヤル１５を回動させる際、カートリッジの交換時期を表示窓５２から見える位置に容易に止められ、交換時期がずれることもなく使いやすい。
さらに、交換表示ダイヤル収納部側面５４の外側にスタート印６２を設け、交換表示ダイヤル１５の使用開始時期カレンダー６１の使用開始日を示す文字をスタート印６２に合わせると、図２６のように表示窓５２から搭載するカートリッジの寿命に対応したカートリッジの次回交換日が表示される構造になっている。使用者がカートリッジの寿命から次回交換日を算出する必要がなく、交換日を間違える心配がない。
交換表示ダイヤル接続部５１を先端の外径が軸中央部の外径より大きい軸形状としている。交換表示ダイヤル１５のフタ接続部７０はフタ１３の交換表示ダイヤル接続部５１に挿入可能な円筒形状で、先端の内径が円筒中央部の内径より小さい形状としているので、交換表示ダイヤル接続部５１中央部の細径がフタ接続部７０先端の小さい内径に嵌り、両部材がかみ合うので、交換表示ダイヤル１５を回動させても外れる心配がない。また、フタ１３の交換表示ダイヤル接続部５１を放射状に４分割しているので、軸中心方向にたわむことが可能となり交換表示ダイヤル１５の脱着が行える。
水抜き穴７２を設けているため交換表示ダイヤル１５内に水道水が溜まることを防止でき、衛生的に保つ効果がある。また、フタ接続部７０を分割し、分割スリットをくぼみの底面まで伸ばした形状にすることでも水抜き効果を得ることができる。
カートリッジ２については、外メッシュ部材３３、内メッシュ部材３４、上開口メッシュ部材３８に関しては、ろ材の粒径よりも細かいメッシュサイズのものを用いているので、ろ材充填部３３への異物の流入、またろ材充填部３３からのろ材の流出を防止できる。流量維持と衛生面から、メッシュクロスの材質はポリプロピレン、ポリエステルなどを原料とした撥水性の高い合成繊維からなる素材を用いる。 The exchange display dial 15 will be described with reference to FIGS. 23, 24, and 25.
